DINE WEIGHT MANAGEMENT PROGRAM IN A WORKSITE SETTING

描述(首席调查员摘要)：在第一阶段 项目，一种计算机辅助教学(CAI)营养分析 发展了一种方法，使个人自己的食物选择和 体力活动可以作为了解心血管疾病的基础 为了增进健康和改善营养。最终的产品是一个全面的 营养教育包，包括营养分析，饮食 改进，有相关活动和食物记录软件程序 手册、营养手册和统计/图形程序。这个 拟议的研究将证明应用程序是否使用 这一综合套餐(餐饮体重管理计划)将产生 长期减肥。从工作现场的一群志愿者员工中 设置，80名员工年龄在20%到35%之间 他们的理想体重，将被随机分配到治疗和 延迟治疗组。治疗组(n=40)将不接受 方案直到研究的实验阶段结束。两个小组都将 在6个月和12个月时进行预测测试、后测试和跟踪测试。 主要的结果指标将是体重减轻和营养摄入量。 体重减轻将使用标准方案和营养素来确定 摄入量将使用食物的三天食物记录来确定 模型辅助访谈(营养协调中心方案)。这个 研究假设是治疗组员工的体重 将从前测下降到后测，并将从后测持续 以进行随访，而对照组员工的体重将 从前测到后测，再到后续，保持不变。分数测量 试验组的营养素摄入量将有所改善，但不会有所改善 在对照组中。数据将使用双侧t检验和 将提供描述性数据。

DESCRIPTION (Principal Investigator's Abstract): During the Phase I project, a computer-assisted instruction (CAI) nutrient analysis methodology was developed so that an individual's own food choices and physical activity could be used as a basis to learn about cardiovascular health and to improve nutrition. The final product was a comprehensive nutrition education package which included a nutrient analysis, diet improvement, software program with a related activity and food record manual, a nutrition workbook, and a statistics/graphics program. The proposed study will demonstrate whether or not an application utilizing this comprehensive package (DINE Weight Management Program) will produce long term weight loss. From a pool of volunteer employees in a worksite setting, eighty employees who are between 20 percent and 35 percent over their ideal body weight, will be randomly assigned to treatment and delayed-treatment groups. The treatment group (n=40) will not receive the program until after the experimental phase of the study. Both groups will be pretested, posttested, and follow-up tested at six months and 12 months. The primary outcome measures will be weight loss and nutrient intake. Weight loss will be determined using a standard protocol and nutrient intake will be determined using three-day food records with food model-assisted interviews (Nutrition Coordinating Center protocol). The research hypothesis is that body weight of employees in the treatment group will decrease from pretest to posttest and will be sustained from posttest to follow-ups, whereas body weight of employees in the control group will remain the same from pre-test to post-test to follow-ups. Scores measuring nutrient intake will improve in the experimental group and will not improve in the control group. Data will be analyzed using two sided t-tests and descriptive data will be presented.
